请分析以下程序。 int main() { pid_t pid; pid = fork(); if(pid==0) printf("I am the child process, my process ID is%d\n",getpid()); else printf("I am the parent process, my process ID is%d\n",getpid());} 那么,该程序正确运行后的结果是A.I am the child process, my process ID is 3744 I am the parent process, my process ID is 3987B.I am the child process, my process ID is 3744C.I am the parent process, my process ID is 3987D.不输出任何信息
对于如下C语言程序 int main() { pid_t pid; int x=1; pid = fork(); if(pid==0) printf("I am the child process, x=%d\n", ++x); else printf("I am the parent process, x=%d\n", --x); } 在UNIX操作系统中正确编译链接后,其正确的运行结果是A.I am the child process, x=2B.I am the parent process, x=0C.I am the parent process, x=2D.I am the child process, x=0
